Simplified Method

A study comparing a three-dimensional extension of the Bishop simplified method with other limit equilibrium solutions is presented. Very good correspondence is found in cases of rotational and symmetric sliding surfaces, such as ellipsoids. The Bishop method tends to be conservative when applied to nonrotational and asymmetric surfaces because it neglects internal strength. The error is, however, tolerably small for many commonly occurring slide geometries. Indices are proposed to identify cases for which the method should not be used. With its limitations defined, the Bishop simplified method offers a useful algorithm for three-dimensional limit equilibrium analysis. Key words: three-dimensional slope stability analysis.

Slope stability analysis is of great significance in geotechnical engineering, for which there are various research approaches as limit equilibrium analysis, numerical analysis, neural network based analysis, etc. Being one of the modern approaches, slope stability analysis based on GIS rises and develops swiftly. Authors give a brief introduction of the theory, research procedures, new developments and try to make it clear the new trend in slope stability analysis. Finally, the slope stability system which was developed based on GIS is introduced. The system which can analyze slope stability based on data mining including fuzzy clustering analysis, regression analysis, extension evaluation etc has provided with more powerful slope stability functions and is easy to be integrated

Analysis Of Stability

As the complexity and the tall of open pit slope, two-dimensional slope stability analysis methods have been unable to meet the needs of the accuracy of stability analysis. Therefore, for the complex situation of Pingzhuang open pit slope, use with three-dimensional rigid body limit equilibrium method to analysisstability of slope.slope3D system, which consists of pre-treatment, limit equilibrium analysis solver and post-processing, the first processing core is to construct three-dimensional geological model of the slope, post-processing mainly results analysis and visualization graphics. The system combined organically the slope engineering geological information three-dimensional visualization and the analysis of stability, which make us to determine the landslide model, reveal the mechanism of landslide more accurately. Make an important contribution for ensuring safety in open pit production, a good foundation for slope stability analysis of other open pit.
